Utility Energy Storage System Blue Series (40-foot-containerized) Blue 500kW280Ah-T1~Blue 630kW280Ah-T1

Utility Energy Storage System Blue Series (40-foot-containerized) Blue 500kW280Ah-T1~Blue 630kW280Ah-T1

This product series are of modular, strings and smart energy storage system design.

Rated system energy: 2.5 MWh (maintenance from the interior); 3.6 MWh (maintenance from the exterior).

The overall degrees of protection shall not be lower than Ip55.

Product in this series enables independent detection for each cell, independent safety management of each battery module, anti-circulation and anti-counter-current between battery clusters. Meanwhile, it also facilitates active equalization, DC side hierarchical multi-level short-circuit protection, local control fast linkage protection, etc.

The grid supports LVRT, HVRT, ZVRT, islanding detection, active and reactive power regulation, PF control, slow start/shut down.

This product series support LAN local monitoring, 4G remote IoT, and cloud platform.
